Kumpf & Meyer Riesling Westerberg Perpétuel is a white wine made by Julien Albertus in Rosheim, Alsace, France.
It is a single-variety Riesling from the Westerberg vineyard, located on the slopes of Rosheim, with a southern exposure and clay-limestone soils. The grapes are directly pressed and the wine undergoes a long ageing in foudre.
Its distinctive feature is the Perpétuel concept: the 2015, 2018 and 2019 vintages are blended in a 4,000-litre foudre, marking the beginning of a solera or perpetual reserve. It is not a conventional blend of vintages, but rather a system designed to allow different harvests to integrate and for the wine to gain complexity and depth over time, with the aim that the Westerberg terroir expresses itself above the differences between individual vintages.
